HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 761,098, datedvMay 31, 1904.

Application filed July 3, 1903. Serial No. 164,173. (No model.)

To a/ZZ whoml t may concern:

Be it known that I, WILLIAM W. PORTER, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Gas-Generating Burners for Hydrocarbons, of which the following is a specification.

This invention relates to gas-generating burners for hydrocarbons, and refers particularly to improvements in the general form and in the construction of such burners.

In the accompanying drawings, Figure 1 is a vertical section taken through a burner embodying the features of my invention. Fig. 2 is a horizontal section on dotted line 2 2 of Fig. 1. Fig. 3 is a transverse section through the hydrocarbon-supply cock on dotted line 3 3of Fig. 1. Fig. 4'is a detail perspective View of the plug of said hydro- 'carbon-supply cock. Fig. 5 is adetail view showing the means for oscillating said plug to open'and close the cock.

In the embodiment herein shown and described the burner is adapted'to be placed in the lire-box of a common cooking or heating stove, liquid fuel instead ofcoal or wood being used to supply heat for cooking or heating. By employing a burner of a larger size a furnace may be operated with liquid fuel and a house warmed thereby.

In constructing a burner according to said invention I provide a body portion 1 cornprising a hollow ring 2, the interior of which ring forms the generating-chamber 3. In the center of the ring 2 is mounted the burner proper, 4, supported from said ring by the web 5, extending inwardly from the lower side of the ring and being integral with said ring and the burner. This web 5 is provided at intervals with air-openings 6, the purpose of which will appear later herein. The burner 4 comprises the mixing-chamber 7 and the downwardly extending bell mouth mixingtube 8, communicating at its Lipper end with said mixing-chamber. The mixing-chamber is in annular form and surrounds the top of the mixing-tube, said tube being supported centrally of the chamber by means of the integral 'connecting-ange 9, which flange is provided with air-intake openings 10. The outer' peripheral wall of the mixing-chamber is perforated with the openings 11, through which gas escapes to pass outwardly beneath the generating chamber 3 and upwardly around the outer side of said chamber. The top of the mixing-chamber is partially closed by means of the bell 12, the bottom edge of which rests upon the inclined seat 13 at the upper edge of the mixing-chamber 7. This lower annular edge of the bell12 is provided with a series of slits or openings 14, through which gas from the mixing-tube may pass, said gas burning in a ring about the bell.

A muiIle-plate 15 is supported within the closing-bell 12 by meansof a bolt 16 passing through a central opening in said plate and bell. Bosses 17, formed upon the upper face of the plate, separate the plate a little distance from the inner top wall of the bell. At its upper end the bolt 16 is bent to form a lifting-ring 18, by means of which the bell may be handled.

Hydrocarbon is supplied to the generatingchamber 3 by means of the supply-pipe 19 and the connecting-pipe 20, a cock 21, to be next described, being adapted to regulate the supply of liquid passing through said pipes. This cock consists of a casing 22, in which a taper plug 23 is seated. The plug 23 is provided with the axial opening 24, communieating with a notch 25, formed by cutting directly into the plug from one side thereof. An opening 26, formed by means of a drill or in any other suitable manner, connects the notch 25 with the axial Opening 24. The plug 23 is provided with 'an operating-stem 27,

which stem at its forward end carries a fork 28, within which an eccentric 29, having a hand-wheel 30, is rotatably supported in any suitable manner. As will be seen, this mechanism provides means for oscillating the plug 23 slightly. The generating-ring 2 is also connected with the gas-cock 31 by means of a pipe 32, the upper end of which pipe extends upwardly within the generating-chamber, so that said chamber may contain the condensation of the hydrocarbon gas and not permit said condensation to drain downward through the gas-pipe 32 into the gas-cock 31;

This gas-cock is similar in general construction to the hydrocarbon-cock 21, having a casing 33, a taper plug 34, with its axial opening 35, its notch 36, and its connectingopening 37, also having a stem 38, an opening-fork 39, an eccentric 40, and a hand-wheel 41. The body portion of the gas-cock is provided with an escape-opening 42 upon its upper side placed axially of the mixing-tube 8 and at its lower side is provided with a boss 43, to which an initial generating-pan 22 is secured by means of a screw 45.

Tn operation hydrocarbon is placed in the initial generating-pan 44 and ignited. Hydrocarbon is admitted through the cock 21 to `the generating-chamber 3, whereby means of 'the heat of combustion rising from the initial generating-pan said hydrocarbon is vaporized. The generated gas passes downward through the gas-pipe 32, through the gascock 31, and upward through the dischargeopening 42 into the mixing-tube 8, where'it is mixed with airand is carried by the force of its discharge into the mixing-chamber 7,3 escaping therefrom throughthe slits 14 in the 'closing-bell -12 and throughthe open- .f ings 11 in the peripheral wall'of the mixingchamber. Heated air also enters the mixingchamber 7 through the openings 10. The gas escaping through the peripheral openingsll burns beneath andv around the generatingchamber 3.l In operation-[the walls of the generating-chamber are made red-hot, and the vapor therein is therefore highly heated. The mule-plate 15, together with the ar.- rangement of openings 11 and I14,v has been found to materially reduce the roaring noise common in burners of this class. i

The quantity of hydrocarbon admitted to the generating-chamber through the supplypipe 19 is regulated, as will be understood. by the hydrocarbon-cock 21. The tapering notch 25 in the plug 23 is turned, as shown'in Fig. 3, with its narrow edge' in coincidence with the supply-pipe 19 just sufliciently to permit the passage of a suitable quantity of liquid. If sediment lodges in the narrow portion of the notch 25, 'it' may readily' be washed away by opening the cock wider. This form of cock has every advantage possessed by a-needle-valve without the liability of the latter to clog and without the tendency that exists in needle-valves to enlarge the discharge-opening.

The supply ofV gas to the burner is4 regulated by the gas-valve 31 in asimilar manner. Both of these valves, being opened by a very slight turn of their plugs, are operated by means of eccentrics 29 and 40 and hand-wheels 30 and 41. ln this construction the hand-wheel may be turned a considerable portion oi' a revolution and the valve-plug be oscillated thereby only slightly. To shut off the burner, both the hydrocarbon-cock 21 and the gas-cock 31 are closed.

I claim as my invention- 1. In a gas-generating burner, in combination, a vgeneratingchamber in hollow-ring form, said ring having a central space open at the top; a burnersupported within'said ring, said burner comprising an annular mixingchamber having subfiame-openingsin itsside walls, said mixing-chamber being below' Vthe plane of the generating-chamber and connected therewith by a web provided with air-intake openings; a removable closing-bell forfthe upper side of said mixing-chamber, having gas-discharge openings in its sides, sai'dubell lying within the open central space of the generating-ring; a mixing-tube communicating with said mixing-chamber; a gas-pipe communicating with the upper portion of said generating-chamber; and a valve in said pipe. 2. 'In a gas-generating burner, in combination,- a 'generating-chamber in hollow-ring form, said' ring having a central space open at the top; `a burner.supportedwithin said ring, said burner comprisingan annular mixingchamber'having subiiame-open'ngs in its side walls, said mixing-chamber being below the plane of the generating-chamber; a removable closing-'bell for the upper side of said mixingchamber, having' gas-discharge openings in its sides, said bell lying within theopen central space of the generating-ring; a mixing-tube communicating with said mixing chamber, saidl chamber having a plurality of air-intake openings adjacent to said mixing-tube; a muffle-plate supported in said' closing-bell above the upper end of said mixing-tube; a gas-pipe lcommunicating with the upper portion of said generating-chamber; and alvalv'e 1n said pipe.
